“I believe Miller is a Clinton Portis clone, with the tools to be a dominant runner in the NFL,” Brooks writes. “He has the speed to turn the corner on outside runs, while also displaying the toughness to pick up the hard yards between the tackles.”

It makes sense — like Portis, Miller also ran track at Miami, and the two have eerily similar builds (Miller is 5-10, 218 pounds; Portis measured up at 5-11, 219 pounds). Portis, of course, was a star immediately, first in Denver, rushing for 1,300+ yards in each of his first four NFL seasons.

It will be interesting to see what type of workload Miller gets[3]; running back appears to be a relatively deep position for the Dolphins, and the offense, in year two with Mike Sherman, likely will continue to evolve. You would expect a team that made such a substantial investment in improving its passing game — the additions of Mike Wallace, Brandon Gibson and Dustin Keller, namely — to de-emphasize the running game, not as indictment of Miller but to allow the offense to reach its optimal effectiveness.

This, though, can be flipped into a positive for Miller. More attention on the outside should mean less bodies in the box, potentially giving the second-year running back the ability to make the most of his opportunities.

“He has exceptional stop-start quickness, which makes him tough to tackle in the hole,” Brooks writes. “With the Dolphins set to use more three-receiver formations to spread the field, Miller’s talents as an all-around runner could shine in Miami this season.”
